The type dimension of Feed Yeast segmentation distinguishes five primary sub‑categories that together shape market volume. Active dry yeast is cultivated for its high viability and is predominantly used as a direct feed additive, contributing roughly 28% of total sales due to its broad applicability across species. Inactive yeast undergoes heat‑inactivation, offering a stable protein source with a lower cost profile; it accounts for about 22% of the market, especially in regions with limited cold‑chain infrastructure. Yeast extract provides concentrated nucleotides and peptides, enhancing gut health and feed efficiency, and represents approximately 18% of revenue, driven by premium livestock operations. Beta‑glucan enriched yeast is formulated for immune modulation, capturing an estimated 16% share as producers target disease‑resistant breeding programs. Finally, probiotic yeast strains such as Saccharomyces cerevisiae var. boulardii deliver live microbial benefits, securing the remaining 16% and reflecting growing interest in microbiome‑focused nutrition. Collectively, these types delineate the market taxonomy and determine pricing dynamics, production capacity, and R&D focus within the Feed Yeast market.
